The invention discloses a method of controlling music playing based on baby shoes. The method comprises the following steps that S1, an BMP value is extracted according to different songs in advance, according to various states of baby crying, the different songs are matched, and the different songs are stored in a storage module so as to mark indexes; S2, gyroscope sensors arranged on the baby shoes swing along with baby feet synchronously, and a counting module is used for counting periodic swinging times of the gyroscope sensors; S3, the counting module sends the swinging times in the step2 to a processing module, the processing module calculates and acquires a swinging frequency range according to the periodic swinging times, and the swinging frequency range matches with the BMP value; S4, the processing module sends the BMP value in the step3 to a play module, and the play module reads the songs corresponding to the BMP value in the storage module of the step S1 according to the BMP value; and S5, the play module plays the songs in the step S4 through a horn. The songs do not need to be selected manually.
